1,1-Di(p-tolyl)ethylene, with the CAS number 2919-20-2, is an organic compound characterized by its structure, which features two p-tolyl (para-methylphenyl) groups attached to a central ethylene unit. This compound is typically a colorless to pale yellow liquid or solid, depending on its specific form and purity. It exhibits a relatively high melting point and boiling point compared to simpler alkenes due to the presence of the bulky p-tolyl groups, which also contribute to its hydrophobic nature. 1,1-Di(p-tolyl)ethylene is known for its stability under normal conditions, but it can undergo reactions typical of alkenes, such as electrophilic addition. Its unique structure makes it of interest in various chemical applications, including materials science and organic synthesis. Additionally, it may exhibit interesting optical properties due to the presence of the aromatic rings, which can influence its behavior in photochemical reactions. Safety data should be consulted for handling, as with any chemical substance, to ensure proper precautions are taken.

1,1-Di(p-tolyl)ethylene (DPTE) is a radical scavenger that can be used to prevent or reduce the effects of oxidative damage. It has been shown to scavenge radicals and crosslink acrylate monomers, leading to a decrease in radical scavenging activity. DPTE also has been shown to have a scavenging effect on atropate radicals and thermally induced radicals.
